Embodiment 1
[0032] Gas or dust combustion and explosion performance test device using super capacitor, its structure is as follows figure 1 As shown, it includes a control terminal and a test terminal. The control terminal includes a series connection formed by a switching power supply 1, a supercapacitor 3, a unit control switch 4, and a total power supply control switch 5 connected in series, and a PLC control system 2 for general control. The test terminal It includes an explosion combustion reaction observation tube 8 and a pluggable heating wire 6 arranged in the observation tube, a powder spraying or air jet dispersing device 10, an infrared thermometer 9, and a discharge top cover arranged on the top of the explosion combustion reaction observation tube 8 7. The two ends of the pluggable heating wire 6 are respectively connected to the series components at the control end, and the powder spraying or air spraying dispersing device 10 is also connected to an external pipe 11, and an e...
Embodiment 2
[0037] Gas or dust combustion and explosion performance test device using super capacitor, its structure is as follows figure 2 As shown, the structure is roughly the same as that of Embodiment 1, the difference is that there are multiple pluggable heating wires 6, and both ends of each pluggable heating wire 6 are connected to a group of series components, and each series connection They are connected in parallel with each other, and are controlled by the PLC control system 2 to heat the pluggable heating wire 6 . By setting multiple supercapacitors 3, unit control switch 4, pluggable heating wire 6 and infrared thermometer 9 on a set of explosion reaction observation tubes, it is possible to test samples at one time and achieve multi-temperature range testing and multi- Channel monitoring, to fully monitor the response of the entire explosion reaction observation tube.
